| Abstract

In the era of ubiquitous computing connected any object to the Internet is increasing day by day. Near Field Communication (NFC) is a perfect example of ubiquitous computing that is secured, short-ranged, low powered contactless communication. Powerless, single-tapping NFC tag is obtaining its popularity exponentially. Massive demand for NFC requires to study implementing this fast-growing technology onto different materials and places. In this research study, NFC implementation on flexible material is investigated with different types of materials. NFC antenna designing with mathematical modeling was executed. Simulation for NFC coil inductance calculation was performed and was verified with mathematical modeling. The NFC antenna was fabricated, experimented, and verified according to mathematical modeling and simulation. NFC antenna has several design parameters on which coil inductance is dependent. In this thesis, these major design parameters are considered, and a factorial design of experiment was conducted to observe which parameters have a substantial effect on the response, i.e., considered here as the read range. After the factorial design of the experiment, it was found that size is the most critical parameter for NFC tag antenna design. Two-way interactions of turn and thickness had the second most significant effect on the read range. Three-way interaction of size, turn, and thickness was the top most influential parameter on the read range. A comparison of available industrial NFC antennas with our fabricated antennas was performed and noticed that our longer sized NFC antennas had a higher reading distance than the former one. The factorial design verifies this comparison result as it depicts size is one of the three main contributing factors of NFC antenna designing parameters. Besides those experiments, another investigation was conducted from the user standpoint to perceive a user’s convenience when using the NFC antennas as posters, and a comparison between two smart posters was concluded. We found that for our NFC poster, 95.5% of users had experienced the longer detection range, and 63.6% of the users believed that our NFC poster had a quicker response. The average NFC poster detection time of the commercial tag was 4.25 seconds, whereas our NFC poster took an average time of 2.04 seconds to connect. All of the experiments and findings in the thesis illustrates that NFC antennas in flexible materials open up a new area of research which enables everyday connectivity with different materials with the smartphone. Furthermore, this type of research enables interdisciplinary research work that requires a combination of antenna and material science research work and commences advanced antenna technology developments towards next-generation mobile wireless communication systems.
